Once you map a monitoring tool to multiple services, Freshservice evaluates alerts received in the Alert Management module to see if they qualify to be associated with a service. If they do, Freshservice will inform you through a banner on the Services List page. You could access these recommendations by clicking on the Potential Services button.
You can then review the candidates recommended by Freshservice, and then approve or dismiss the suggestion.
Potential and dismissed services older than 30 days will automatically be deleted and moved to trash. A scheduled job will run every Sunday to remove these services from the system.
